Definitions

  • This invention relates to rolls made of non-woven cloth in which high molecular material fiber yarns such as polyester, nylon, acrylic and polypropylene are bound with natural fiber yarn such as rayon, cotton and wool by a resineus binder and heat treatment.
  • the nonwoven cloth is cut to in a desired size, is laminated or stacked onto a shaft made of iron, plastics or wood and is axially pressed together to form a roll.
  • the non-woven cloth elements pressed together to make a molded roll of a large coefficient of friction and high shearing stress.
  • the coefficient of friction obtained by the nonwoven roll of the invention is remarkably high compared with that of conventional rubber rolls.
  • the surface hardness of the non-woven roll can be made as desired due to the degree of compression applied when the laminated and mounted non-woven cloth elements are molded, on the basis of the elasticity of the material of the non-woven cloth.
  • the construction of the nonwoven cloth roll is quite uniform as well as the hardness of the roll, due to the non-directional fiber organization of the non-woven cloth.
  • the heat-resistivity is good enough according to the material of the non-woven cloth.
  • a non-woven cloth is made of nylon 43 parts, cotton 18 parts, resinous binding agents 39 parts.
  • the coefficient of water absorption is 8.2 percent, the weight per unit area ZOOfiO gram/m the thickness 1.07 mm and the tensile strength l5.0kg/Scm.
  • a non-woven cloth is made of nylon 28 parts, polyester 28 parts, rayon 14 parts, resinous binding agents 30 parts.
  • the coefficient of water absorption is 52.6 percent, the weight per unit area 180:50 gram/m the thickness 2.60 mm and the tensile strength 5.5 kg/Scm.
  • the non-woven cloth roll of subject application can be utilized in manufacturing pinch rolls, such assnubber rolls, deflector rolls, tension bridle'rolls, wringer rolls, squeezer rolls and wiper rolls.
  • FIG. 1 shows two embodiments of an element of the non-woven cloth roll of the subject invention
  • FIG. 2 is a perspective view of the non-woven cloth roll of the subject invention
  • FIG. 3 is a schematic arrangement of rolls used for measurement of the characteristics of the non-woven cloth roll of the subject invention.
  • FIG. 4 shows the characteristic curve of the nonwoven cloth roll of the subject invention. cl DESCRIP- TION OF THE PREFERRED EMBODIMENTS;
  • non-woven cloth elements 1 and 1' shown in FIG. 1 are of 1.07 mm to 2.60 mm thickness.
  • the elements are cut from a sheet of cloth material and elements 1 and 1' are laminated or stacked onto a shaft- For Pinch Roll For Oiling Roll Hardness 83 i 2 55 2 5 (JISK 630i) Poisson's ratio 0.5 0.3 Module of shearing elasticity 33 30 Coefficient of water absorption 5.8 50.6 Shearing stress l200kg/cm 680-720
  • the most distinguished features of the roll of subject invention are the large coefficient of friction and the high shearing stress.
  • FIG. 3 The large coefficient of friction is verified by using a testing machine of the type diagronmatically shown in FIG. 3.
  • a steel plate 4 of 1.2 mm thickness with palm oil painted on the surface thereof is introduced at 5 and is taken out from an outlet 6 in the direction shown by the arrow.
  • Two pairs of tension bridle rolls 7 and snubber rolls 8 are provided between 5 and 6 and steel plate 4 is passed through the nips'defined by each associated roll 7 and 8.
  • the magnitude of the tension at intake 5 is zero and at outlet 6 is 3.5 tons.
  • Snubber rolls 8 is pressurized with a force of 3 tons as shown by arrow.
  • the angle of deflection of the steel plate is 320 and the speed of the steel plate which passes through the rolls is 400 m/min.
  • the roll of the subject invention makes it possible to treat the steel plate or the like at a high speed without causing any slippage occuring in the steel manuacturing line and any fault such as plate break or plate fold at a high speed which usually accompanies slippage does not exist at all.
  • the large coefficient of friction of the roll causes close adhesion of the roll to the steel plate so that when the roll is utilized as an oil squeezer roll, in the squeez ing operation, the oil film deposited on the steel plate is squeezed sufficiently to leave only a thickness of the oil film necessary for prevention of rust formation on the steel.
  • the full line l denotes the resultant data of the roll of the subject invention and the dotted line II denotes that of a conventional rubber roll.
  • the curves in FIG. 4 teach that oil quantity of the steel plate squeezed is reduced from I liter/ton to 0.46 liter/ton by means of the roll of the subject invention, making a reduction of 64.8 kilo liter a month with a series of lines, in which steel plate of 120 kiloton is processed a month.
  • the roll of the subject invention When the roll of the subject invention is used as a squeeze roll provided in the outlet of a water washing line, the slippage due to hydroplaning phenomena does never occur because of the large coefficient of friction so that the water is squeezed from the steel plate to a remarkable extent.
  • the roll of the subject invention as an oiling roll, two kinds of rolls are combined to constitute a pair of rolls, in the combination the oil being applied at the inlet of the rolls and the excess part of the oil being squeezed at the outlet of the rolls so that any fault due to a trace of oil appearing in the direction of advancing the steel plate at a higher processing velocity is eliminated to fully reduce the rust.
  • a pair of rolls with large coefficient of friction was used at the outlet to successfully improve the adhesion of the roll to the steel plate and to uniformly apply the oil onto the steel plate.
  • the shearing stress of the roll of the subject invention amounts, for example, to 1,200 kg/cm as compared with 620 kg/cm obtainable in a conventional rubber roll and, therefore, no tearing off of the roll results. This means that the full working duration of a single roll can be extended and also the expense for changing the roll is abolished.
  • a roll comprising a shaft having an axis and a plurality of annular disc elements of a non-woven fabric, the fabric consisting of yarns of fibers of a high molecular synthetic resin material and of natural fibers, and a resinous material binding the yarns together, the elements being stacked on the shaft and axially pressed together to form the roll, the improvement comprising the elements being heat treated and axially pressed together so that the roll has a Poissons ratio of about 0.5 and a shearing stress of about 1,200 kg/cm".
  • the roll of claim 1 having a hardness of 83: 2 and a coefficient of water absorption of about 5.8 percent.
